' The' hides or to be dyed are placed on a circulart'able which is preferably d1v1ded into six compartments; but a larger or smaller number of compartments can be used, if de-v 'o,sired. The said table isyintermittently revolved with intervals of rest after each sixth "of arevolution; "During e'ach interval of rest I an attendant places an undyed hide in one of 'the compartments. Y During the next time val of rest this hide isacted on by amordant supplied by means of a splrayer. "Thereupon the said hide is moved byithe table into a. po-

By means of the 'pulleysO' 'curvilinear motion is impartedto the spra ers in the manner which will'be described erein- 5 the lever beingtransmitted, by means .of a connecting-rod- R, to a lever S, which is 1 es a f treating the i1 is movable relativel to'the pipe '5 and can be that the belt K. is shifted each time the table series of rollers Y, trave mg ina circular race outline one of the hides to be this purpose the tube is connected with a rod n, on w one of the central pulleys is guidedby means of studs T, which extend throu h slots formed in the slide. To the slide T are fixed two arms U, between which passes the driving-belt K, and the slide is engaged by a lever V, which is pivoted at V and adapted to be operated by rojections X, fixed to the under surface of t e table A, so

makes onesixth of a revolution. Since the table A is in most cases of considerable diameter, it is preferably sup orted by means of a Z of U-shaped cross-section supported by pedestals Z. It is essential that the sprayers should only be in action intermittently during the periods at which the table is stationary. During the rotation of the'table the s rayers must be put out of action. This is e ected in the following manner: To the hub E is fixed a sleeve a, to the 11 per end of which is fixed a cam b, Figs. 1 and 3. A short distance above the said earn 1) a plate or spider c is mounted on the pillar F. The arms of the said as ider, which are preferably ribbed, are provide with central slots 0''. In each of the said slots 0' there is slidable a vertical rod (2, which serves as an axle for a roller (2, the latter being kept in contact with the cam b by means of a springs, bearing against a bail 9, connected with the said axle. The lower ends of the axles d are guided by means of a slotted plate f. To each bail 9 there is fixed a curved rod g, connected to the lever h of a cock 7t, adapt, ed to control one of the pipes i, which su ply the mordant d e, and other liquids use for 4 id es. Each of the said pipes is I rovided with an additional cock j, adapted to e operated, if necessary, by means of a handle 9', but normally the cooks 1 remain open. To the lower end of each pipe 6. a tube It, terminatin in a rose 7c, is connected by means of an in ia rubber union, so that the said tube caused, by means o a earn 1, to

travel through a sinuous path substantially resembling in treated. For

ich is mounted a roller kept in contactwith the caml by means of a spring m, connected with the said rod, the latter being connected with a ulley o, revoluble on the pipe 71 and adapts to be driven by means'of 0. The pipe i and s rayers k ls are supported by means of suita le framework p with braces and stays to afford the necessary rigidity and strength. The illar I is preferably made hollow in order that it can contain the pipes i, which supply the mordant, dye, fixing liquid, water, or the like to the pipes i. This arrangement is, however, not essential, inasmuch as the said liquid can, if desired, be supplied by means of conduits arranged above t e apparatus or in any other suitable position.

The action of the, apparatus is as follows: In the position shown in Fi s. 1 and 2 the driving-belt K drives the puIleys J, J, and L, so that the shaft M is revolved'and 0 erates the worm N and the ulley O. The atter operates the pulleys 3 and 0, so that all the sprayers is k are caused to act on the hides placed on the table A, the cooks h being at this stage of the operation open. The rotation of the worm N and worm-wheel N causes the projection P to act on the levers Q and S, so that the slide T is operated and shifts the belt K, by meansv of the arms U from the pulle J 2 to the loose pulley J and thence to the I is driven. The latter transmits its movement by means ofthe worm I and Wormwheel I to the shaft H, pinion G, and bevelwheel G, so that the table A is rotated, together with the cam b, and the latter oper ates the rods .9 in such a manner that the cooks I I. are closed. Meanwhile the cessation of the rotation of the shaft M causes the movement of the sprayers to be discontinued. When the table A has made one-sixth'of a revolution, one of the projections X operates the lever V and the slide T in such a manner that the belt K is shifted back to the pulle J the rotation of the pulleyJ and shaft 2 being stopped by means of a suitable brake q. At this stage of the operation the position of the earn 1) is such that the cocks h are opened, so that the sprayers act on tho hides and continue in action until the projection P a sin causes the table to rotate; The loose pu ley J allows of putting the ap aratus out of action without stopping the iving-belt, and a handle 1' allows of o crating the slide T by hand, if necessary. t is obvious that the intermittent rotation of the table and action of the sprayers can also be produced by other mechanical meansfor instance, bymean's of toothed wheels provided with gaps or by means of a cam controlling a bifurcated lever adapted to shift the driving-belt. The essential features of the action are the intermit tent rotation of the table A and the alternate opening and closing of the cocks controllin t 1e Sprayers. The devices by means of Whic this action is produced can be varied according to the particular circumstances and re quirements of each case.

What we claim as our invention, and desire to secure by Letters Patent of the United States, is-

1. In a dyein apparatus the combination of a table divi ed into a plurality of compartments for reception of the articles to be treated and adapted to be intermittently rotated through suitable fractions of a revolution, a plurality of sprayers adapted to discharge mto sald compartments, means for conveying various liquids to said spra ere, cocks controlling the latter and means whereby said cocks are automatically opened when 7 'tion, a plurality of Sprayers adapted to dis I charge into said compartments, means for conveying various 1i 'uids to said Sprayers,

the table is at rest andclosed when the table 7 rotates substantially as described.- i
